Unauthenticated console source disclosure via missing server gate

Published Sep 2, 2026 · Updated Sep 2, 2026

Information disclosure in TSI Coop TSI DPDP CMS 0.5.0 and earlier allows remote attackers to read console source without credentials. InterceptingFilter protects only /api/*, so requests for 17 static admin and DPO pages bypass server authentication before client JavaScript redirects. Direct HTTP requests expose endpoint paths, dispatch names, parameter schemas, and role-routing logic, but protected API operations and user data remain inaccessible.
